epaselect epa05071656 Protesters outside of the Baltimore City Circuit Court House East after the jury deadlocked in the trial of Baltimore Police Officer William G. Porter in Baltimore, Maryland, USA, 16 December 2015. A jury in Baltimore failed to reach agreement in the first trial of six police officers charged in the killing of an African-American whose death last year in police custody touched off demonstrations and rioting. The judge in the case declared a mistrial after the jury could not come to agreement on four charges against police officer William Porter. Porter, 26, who is black, faced charges of involuntary manslaughter, reckless endangerment and assault in the death of Freddie Gray. Porter and the five other defendants have pleaded not guilty.
